Front

Which species’ DNA is most similar to the DNA of the toothed whale?

Back

Baleen Whale

Front

What conclusions can be made based on the genetic relationship table?

Back

The red panda and the raccoon are the most closely related.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures have similar structure with different function, while analogous structures have different structure with similar function.

Front

What does the similarity in embryos of chickens, fish, and humans suggest?

Back

They all evolved from a common ancestor.

Front

What event reduces competition by eliminating many species at once and leads to diversification?

Back

Mass extinctions.

Front

Define homologous structures in biology.

Back

Structures that share a common ancestry but may serve different functions.

Front

Define analogous structures in biology.

Back

Structures that serve similar functions but do not share a common ancestry.

Front

What is the significance of gill pouches in embryonic development?

Back

They indicate a common evolutionary ancestor among different species.

Front

How do mass extinctions contribute to biodiversity?

Back

They eliminate many species, allowing for new species to evolve and fill ecological niches.

Front

What is the role of genetic similarity in determining evolutionary relationships?

Back

Genetic similarity helps to identify how closely related different species are and their common ancestry.
